Are sodium-ion batteries a potential energy storage solution?

In this situation, sodium-ion batteries (SIBs) have been considered as prospective energy storage solution in the near future [3, 8]. However, the heavier mass and larger radius of Na ions (Na+ at 1.02 Å, compared to Li + at 0.76 Å) result in slower diffusion kinetics of sodium ions and larger volume change in the electrode materials.

What is a good voltage potential for a Na ion battery?

For anode materials, it is logically required that the voltage potentials should be low, typically in the range of 0.0–1.0 V vs. Na + /Na. Three types of materials have been studied for Na-ion batteries. These include: (1) carbonaceous materials, including hard carbon, soft carbon, graphene and carbon nanofibres; (2) sodium alloys.

Can sodium ion batteries be used in practical applications?

Compared with Li-ion batteries, the development of sodium-ion batteries for practical applications is still in its infancy. The difference in structural competitions for different Na-compound cathode materials presents opportunity for interesting new Na-intercalation materials.
